The 116th Guards Artillery Regiment had been replaced by the 382nd Guards, 1453rd, and 1821st self-propelled gun regiments by 1945.

The 1504th Guards Anti-Tank Regiment was no longer with the corps in 1945.

The 11th Guards Motorcycle Battalion and 1699th Anti-Aircraft Regiment had been added to the corps by 1945.

Depending on the specific tasks allotted to the Corps, units from the STAVKA Reserve could be added to help it achieve its mission. When the 1st Guards Mechanized Corps returned to the front in January 1945, its tank formations were completely equipped with American M4A2 ShermanLend-Lease tanks.

The Corps had been re-designated the 1st Guards Mechanised Division by March 1946 and served in the Transcaucasian Military District before being reorganised as 2nd Guards Motor Rifle Division in 1957 and then 100th Guards MRD in 1965. At some point afterwards, probably in the late 1980s, it was renamed 171st Guards District Training Centre. It was based in Tblisi throughout the postwar period.

After the fall of the Soviet Union, it was redesignated as the 137th Military Base, and finally withdrawn and disbanded in the 1990s.
